What Is Sciatica, Exactly?
Sciatica is not a condition on its own. It is a symptom that shows up when something presses on or irritates one of the nerve roots that form your sciatic nerve, the longest nerve in your body. This nerve starts in your lower back, runs through your buttock, and travels down the back of each leg.
When one of these nerve roots is compressed, you may feel pain, tingling, or numbness anywhere along that path. According to the Cleveland Clinic, sciatica is nerve pain from an injury or irritation to the sciatic nerve that can involve tingling or numbness in your back or buttock that radiates down your leg. It is also worth knowing that this is one of the most common causes of leg pain that people seek medical care for, so if you are dealing with it, you are far from alone.
What Causes Sciatica to Occur?
The root cause of sciatica almost always comes down to pressure on a nerve root before it joins the sciatic nerve. Despite its name, sciatica is usually not a problem with the sciatic nerve itself. In most cases, it is caused by compression of one of the nerve roots that make up the sciatic nerve, typically the last lumbar nerve root or the first sacral nerve root, as they exit the spine. Doctors call this radiculopathy, a term for nerve pain caused by pressure on a spinal nerve root close to where it leaves the spine.
The Most Common Cause: Herniated Discs
The most common cause of this nerve compression is a herniated lumbar disc. When disc material bulges out of its normal space, it can press directly on a nerve root. This can happen after an injury or heavy lifting, but often there's no clear trigger at all. Most people simply wake up one day with pain radiating down one leg, with no memory of an event that caused it.
Other Common Triggers
Beyond herniated discs, several other conditions can put pressure on these nerve roots:
- Bone spurs, which are bony overgrowths that can develop on the spine as we age.
- Spinal stenosis, a narrowing of the spinal canal that pinches nerve roots.
- Spondylolisthesis, where one vertebra slips forward over another, narrowing the space nerves pass through.
In rarer cases, the nerve can be compressed by a tumor or damaged by a disease like diabetes, which is one reason a proper diagnosis matters.
Sciatica Causes and Symptoms: What to Watch For
Recognizing sciatica early can help you get treatment before symptoms worsen. Common signs include:
| Symptom | What It Feels Like |
|---|---|
| Radiating pain | Sharp or burning pain that travels from the lower back through the buttock and leg |
| Numbness | Reduced sensation in the leg or foot, sometimes in just one spot |
| Tingling | A pins-and-needles feeling along the nerve's path |
| Muscle weakness | Difficulty lifting the foot or leg, or a feeling of heaviness |
Sciatica symptoms can affect your lower back, buttock, and legs, and you may also notice symptoms reaching your feet or toes. It's common for one part of the leg to hurt while another part feels numb at the same time.
Who's at Risk for Sciatica?
Certain factors make sciatica more likely to develop:
- Age. Age-related changes in the spine, such as herniated discs and bone spurs, are the most common causes of sciatica
- Excess body weight, which adds stress to the spine.
- Occupation. Jobs involving frequent twisting, heavy lifting, or long periods of driving may play a role.
- Prolonged sitting. People who sit for long periods or lead a sedentary lifestyle are more likely to develop sciatica than active people.
- Diabetes, which raises the risk of nerve damage.
The good news is that several of these factors, like posture, activity level, and how often you take breaks from sitting, are within your control.
How Interventional Pain & Spine Center Approaches Sciatica
At Interventional Pain & Spine Center, Dr. Mohammad Ali and his team focus on finding the specific source of nerve compression rather than simply masking the pain. Depending on what's driving your symptoms, treatment may include:
- Epidural steroid injections, which deliver anti-inflammatory medication directly around the compressed nerve root, often used for sciatica caused by a herniated disc.
- Selective nerve root blocks, which target the exact nerve root causing pain.
- Physical therapy and rehab, to build strength and flexibility that support the spine.
- Radiofrequency ablation, for longer-lasting relief when other treatments haven't worked.
Because Dr. Ali is triple board-certified in pain medicine, neurology, and clinical neurophysiology, he's able to pinpoint exactly which nerve root is involved before recommending a treatment plan.

What causes sciatica to come on suddenly?
Sciatica can appear suddenly after lifting something heavy, twisting awkwardly, or even without any clear trigger at all. Many people notice pain radiating down one leg after simply waking up one morning, with no memory of an injury.
What are the early warning signs of sciatica?
Early signs of sciatica often include tingling, numbness, or a burning sensation that starts in the lower back and travels through the buttock and leg. Some people also notice mild weakness when lifting the foot or leg.
Can sciatica be prevented?
While not every case of sciatica can be prevented, staying active, maintaining good posture, taking breaks from sitting, and managing your weight can lower your risk of nerve compression in the spine.
